The ASI715MC is a sensitive color camera with a 1/2.8" sensor and 8.46 megapixel resolution. With the Sony STARVIS technology used, this camera has low readout noise (0.72e) and ultra-high sensitivity, making it ideal for astronomical imaging of the planets and smaller deep-sky objects and also for microscope photography.
High Transmission Speed
The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR cache to ensure stable and secure data transmission.
USB 3.0 Port & ST4 Guide
USB 3.0 Port: Provides 5Gb bandwidth to allow ASI715MC to run at 45.1fps (10bit, high speed mode)
ST4 Port: Can be used to connect with the auto guide port of mount for guiding
Readout Noise
Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better.
As can be seen, the readout noise of ASI715MC is very low. As the gain value goes high, the readout noise goes down.
Quantum Efficiency
The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio.
According to our estimation, the QE peak value of ASI715MC is about 80%.
